The quality of the brewed fresh beer is very much related to the fermentation. If the fermentation is good, the beer produced will definitely be good; otherwise it will be very bad. Today I will introduce you to the characteristics of the fermenter and the fermentation process.
Characteristics of the fermentation tube:
The wine control valve: the fermenter will have a wine valve, so that we can use it directly as a wine dispenser.
Refrigeration system: It is convenient for us to control the beer temperature and ensure the quality of the brewed fresh beer.
Manhole: You can add hops and make it easy for everyone to observe the wine level, so as to determine the time of the next wine, there will be no broken wine.
Pressure gauge: It is convenient for everyone to observe the pressure inside the tank and make corresponding measures in time.
Thermostat: used to regulate beer temperature. Make yeast fermentation more complete.
Safety valve: The insurance measures can automatically discharge pressure to prevent the air pressure from being too high due to personnel operation errors.
Fermentation process of fermented fresh beer fermenter:
1. Temperature control: Different fermentation temperatures have their own advantages and disadvantages. Low temperature fermentation is used. The yeast produces less by-products during the fermentation process, which makes the beer taste better, the foam condition is good, but the fermentation time is long; the high temperature is adopted. Fermentation, yeast fermentation speed is faster, fermentation time is short, equipment utilization is high, but more by-products are produced, and beer taste is poor.
2. Control of concentration: The change of wort concentration is affected by fermentation temperature and fermentation time. If the fermentation is strong and the sugar-reducing speed is fast, the fermentation temperature can be appropriately lowered and the holding time of the maximum temperature can be shortened. Conversely, the fermentation temperature should be appropriately increased or the holding time of the maximum temperature should be extended.
3. Control of fermentation time: The fermentation time mainly depends on the change of fermentation temperature. When the fermentation temperature is high, the fermentation time is short; when the fermentation temperature is low, the fermentation time is long.
These are the characteristics of the fermenter and the fermentation process.
Reader Urinalysis Reagent Strip
Urine test strips include test parameters for Nitrite, PH, Glucose, Protein, Occult Blood, Ketone, Bilirubin, Urobilinogen, Specific Gravity, Leukocyte, Ascorbic Acid, Ca, Creatinine and Microalbumin.
Urinalysis Test Strips Parameters is a basic diagnostic instrument used to determine pathological changes in the urine of standard urinalysis. urine test strip comprise of up to 12 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample.
The test can be read between 60 and 120 seconds after dipping. Routine testing of the urine with multiparameter strips is the first step in the diagnosis of a wide range of diseases.
A wide range of applications, such as fitness, sports,drinking water, food, cooking oil
[Test Result Explanation]
Urobilinogen:This test area will detect urobilinogen in concentrations as low as 3μmol/L (approximately 0.2 Ehrlich) in urine.The normal range with this test is 3-16μmol/L.A result of 33μmol/L represents the transition from normal to abnormal, and the patient and/or urine specimen should be evaluated further. The negative results of this test cannot determine that there is no urobilinogen in samples.
Bilirubin:Normally no bilirubin is detectable in urine by even the most sensitive methods.Even trace amounts of bilirubin are sufficiently abnormal to require further investigation.Metabolites of drugs which give a color at low pH,such as pyridium and lodine etc,will interfere with the test of bilirubin,high concentration of ascorbic acid may cause false negative.
Ketone:The test strip reacts with acetoacetic acid in urine.It does not react with acetone or B-hydroxbutyric acid.Normal urine specimens usually yield negative results with this reagent,false positive results may occur with urine specimens which containing pigment or large amounts of levodopa metabolites.
